LOUIS o. RODIER, or DETROIn MICHIGAN.

RADIATOR.

SPECIFICATION forming part of Letters Patent No. 292,362, dated January 22, 1884.

Application filed October 1, 1883. (No model.)

.T) all whgm it may concern:

Be it known that I, Louis 0. RODIER, of

Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Radiators; and I do hereby declare that the following is afull, clear, and exnations of the parts, all as more fully hereinafter set forth. t

Figure 1 is a plan of one section of areturn-coil partially broken away at the hub.

Fig. 2 is a cross-section on the line as as, Fig. 1. Fig. 3 is an elevation of a stack or nest of my radiators, with the top coil in section.

In the accompanying-drawings, which form a part of this specification, A represents a single radiator-coil, which is provided with the hollow hub ct ator about its longitudinal center. WVithin this hub I rigidly secure the diaphragm B, which divides the hub and one leg of the radiator into two compartments, as is clearly shown in the drawings. When but one coil is employed, it is connected at the hub, upon opposite sides of thediaphragm, by suitable pipes leading to the boiler. The water enters through the hub and strikes upon the top of the diaphragm, by which it is defiected into the radiator and compelled to travel entirely around through both legs thereof and discharge through the hub beneath the diaphragm. When a nest of these radiators is used,.the hubs of the series are connected together by nipples O, the upper and lower members of the series being connected to the supply and discharge pipes, and the whole mounted upon any suitable base. In short radiators, owing to the hubs being in their v longitudinal and transverse centers, they will be sufficiently supported by their hubs; but in stacks, where they are of any considerable length, their ends should be supported by proper steady-blocks, D.

A radiator-may be constructed of an y desired size, singly or in nests, and water be circulated continuously through any number, the

water being compelled to flow successively from one'to another throughout the entire serles.

I am aware of Patents Nos. 176,056 and 265,279, and make no claim to the construction shown therein, as I deem my invention essentially different therefrom, and believe that it possesses decided advantages over the devices shown in said patents. By constructing a radiator of the form shown, and providing the same with a hollow hub at its longitudinal and transverse center, instead of at one end, the same can and will be supported by the hub independent of other supports,

although when the coils are very large supports may be used at the ends, asshown in the drawings, so that when arranged in stacks the hubs prevent the coils from sagging and serve to keep them level, thus insuring a certain and continuous flow of water through the entire series.

hat I claim as my invention is- 1. A hollow link-shaped radiator, A, having ahollow hub at its longitudinal and transverse center, within which and one leg of the radiator is placed a diaphragm, dividingthem into two compartments, substantially as described.

' 2. .Two or more radiators, A, having hollow hubs at their longitudinal and transverse centers, constructed substantially as described,

each of which "is provided with a central hub LOUIS 0. Roman.
